Notepad++ wildcard in find/replace

Question

I have multiple lines with values like:

F9 23
F9 41
F9 32
F9 12

Those values change in many lines, I need change them to:

F9 23 text
F9 41 text
F9 32 text
F9 12 text

I try:

• find: F9 .*.*.*
• replace:

But i've no idea how i can replace and keep the original value after F9 and add a text after it.

Answer 1

• Ctrl+H
• Find what: ^F9\h+\d+\K
• Replace with: text # a space then the text to be added
• check Wrap around
• check Regular expression
• Replace all

Explanation:

^           # beginning of line
  F9        # literally
  \h+       # 1 or more horizontal spaces
  \d+       # 1 or more digits
  \K        # forget all we have seen until this position

Result for given example:

F9 23 Text
F9 41 Text
F9 32 Text
F9 12 Text
